[0029] Working principle: When installing the junction box, the staff first aligns the installation block 2 with the installation surface. After determining the position, the box body 1 is fixed to the installation surface by bolts, and then the fixing block 8 is inserted into the connecting groove 15. At this time, the fixing block 8 is squeezed and the spring 16 contracts. When the fixing block 8 reaches the bottom of the connecting groove 15, the spring 16 rebounds, so that the box cover 6 and the box body 1 can be assembled and connected. The box body 1 and the box cover 6 are firmly closed. When the junction box needs to be inspected and repaired, press the button 11 on the surface of the box cover 6 by hand, and the retaining piece 13 contacts and squeezes the fixing block 8. At this time, the spring 16 contracts, and the fixing block 8 is pressed below the stop block 14, and it can be disassembled at this time. The anti-collision pad 9 and the buffer strip 10 inside the box body 1 can prevent the wires or cables inside the junction box from loosening or vibrating and causing excessive friction with the junction box, thereby causing wear or damage to the insulating layer and causing electrical failures. The soft pad 17 can play a role in buffering and protection, thereby improving the protectiveness of the junction box.
